Score de pérennité

Pérennité solide

72/100

Strong future-proofing (72/100) — this build should stay relevant for years without major surgery.

Upgrade path75

DIY build — the CPU, motherboard and PSU can each be upgraded independently without replacing the whole system.

Expansion100

Expansion headroom: 3 PCIe slot(s), 4 M.2, 0 SATA, 2 drive bay(s), 0 RAM slot(s) free.

Storage growth70

Storage is 4% utilized with 2 free drive bay(s) and 0 free SATA port(s).

Memory growth20

0 RAM slot(s) free; memory is 98% utilized.

Networking80

Networking is 2500 Mbps, and a free PCIe slot can add a faster NIC later.

Replacement ease90

ATX form factor with standard, socketed components — most parts are easy to replace.

Workload change70

No GPU, but there is room (3 PCIe slot(s), PSU headroom 1.8x) to add one for AI/transcoding.

Score de risque homelab

Risque modéré

37/100

Moderate risk (37/100) — a few items are worth fixing before you commit (see checklist).

critical

Single point of failure

All data sits on a single drive with no redundancy — one failure means total loss.Solution: Add at least a mirror (RAID 1/ZFS mirror) for irreplaceable data, or an additional parity drive for larger arrays.

low

Storage risk

Solid-state storage — no moving parts, low mechanical failure risk.Solution: For an always-on system, prefer NAS/CMR-rated drives; monitor SMART and replace before the warranty ends.

high

Data loss risk

1 drive(s) with no redundancy — a single SSD/controller failure can still lose data.Solution: Add redundancy and an off-site/off-box backup for anything irreplaceable.

low

Power risk

PSU is 300W, peak load 164W (55%).Solution: PSU sizing leaves healthy headroom for spikes and future parts.

low

Network risk

Single 2500 Mbps NIC — a switch/port failure takes the box fully offline, and multi-user media can saturate 2500 Mbps.Solution: Consider a second NIC or a managed switch; for heavy media, plan for 2.5/10G before the build.

low

Expansion risk

3 PCIe, 4 M.2, 0 SATA, 2 bays free.Solution: Healthy room for future drives, NICs and accelerators.

low

Upgrade risk

2024 platform — current generation with a forward-looking socket/feature set.Solution: Buy for the workload, not the socket — upgrade paths are a bonus, not a guarantee.

Critique

Check the balance

Total (2166€) exceeds your budget (1400€) by 766€ (55%). Ranking already prefers in-budget variants — this one is shown for comparison; check the value variant or raise the budget.Action: Reconsider the config for the stated workload or budget before buying.balance

Critique

Check the balance

This build may struggle with the stated workload.Action: Reconsider the config for the stated workload or budget before buying.balance

Critique

No storage redundancy

1 drive(s) with no mirror or parity for the data you plan to store.Action: Add at least a mirror for irreplaceable data before you migrate anything.storage

Critique

RAM is nearly exhausted

The workload needs 98% of available RAM — swapping will hurt.Action: Add more RAM now, while slots are still free.memory

Optionnel

Add a UPS

An always-on server holding data should survive power blips.Action: Add a line-interactive UPS sized for the build's peak draw (≥ 10 min at typical load for a clean shutdown).power

Optionnel

Keep a backup off-box

Redundancy inside the box does not survive fire, theft or a whole-array fault.Action: Mirror the important data to an external drive, a second box, or cloud.storage

Futur

Drive bays remain

2 drive bay(s) free for future capacity.Action: Expand capacity in pairs (mirror/parity) when needed.storage

Futur

PCIe slot available

3 free PCIe slot(s) for a NIC, HBA or GPU later.Action: Use it for a 10G NIC, extra HBA, or an accelerator when the need appears.expansion

Ce qui devient la limite

RAM is maxed out is the most likely thing to date this build within 1-2y.

1-2y

RAM is maxed out

Pourquoi: All RAM slots are used and the workload already sits at 98% — the next memory need means replacing kits or a new build.Que faire: Buy a single larger kit now, or plan the RAM for the full lifecycle.
